Revit 2014 - Interior Lights button not working?

[Takoko]

So, usually I figure out my problems through a web search, but I haven't found anything on this and I was hoping to know if I am just doing something wrong, or I have a bad install, or if others are experiencing this as well.

I am doing a trial of Revit 2014. Usually I get the student version, but I enjoy 30 days with no stamp. I want to do some night renders, and so I dropped in studio lights that aren't showing up at all in the "sun and artifical" render.

I go to adjust the lights with the "Artificial Lights" button and nothing. No response at all. It's like a fake button that just looks like it's being clicked. Am I the only one?

It seems my file was somehow corrupted. I tried to render in cloud and it gave me an error about the file, which tipped me off. I started a new project and everything seems to be working now. 

Hope this helps somebody else.
